Federal sources tell CBS 11 News that law enforcement officers have confiscated a large cache of weapons found in an apartment near the federal building in downtown Dallas.

...

Police are still taking inventory of all the weapons seized. Among those discovered were two AK-47 rifles, an Uzi 9 millimeter submachine gun, a TEC-9 submachine gun, a 40 millimeter ordnance launcher, a handheld ordnance launcher, and about 500 rounds of ammunition.

Police seized the weapons even though they say it's possible for all of them to be legal.

Child pornography was also found in the apartment, which could lead to criminal charges.

Authorities tell us the tenant travels to the Middle East frequently and just returned from there this morning.

However, authorities say there is no reason to suspect terrorism as a motive.
